THREAD-GUIDE FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 770,123, dated September 13, 1904.

Application filed February 24, 1903. Serial No. 144,856. (No model.)

To all whom it may concern:

Be it known that we, GEORGE SKINNER, engineer, residing at 19 Russell street, and FRED- ERIC HARDMAN, engineer, residing at 154 Waterloo street, Bolton, in the county of Lancaster, England, subjects of the King of Great Britain and Ireland, have invented new and useful Improvements in and Relating to Thread-Guides for Spinning, Twisting, Doubling, and WVinding Frames, of which the following is a specification.

This invention relates to improvements in and relating to thread-guides for spinning, twisting, doubling, and winding frames, and is particularly applicable to ring spinning and doubling machines for cotton and like fibers, the object being to provide improved thread-guiding arrangements in which the thread-guide is capable of beingturned about itself from or into the operative position, as may be requiredin the first place so as to be out of the way while dofiing isbeing performed and in the second place to be turned into position when spinning, doubling, or winding operations are being carried on in the normal way.

A further object of the invention is to provide improved thread-guiding arrangements in which there is little or no possibility of flufi or fly from the yarn or thread gathering around the thread-guides proper and interfering with their proper action.

Our invention will be fully described with reference to the accompanying drawings, in which Figure 1 is an end elevation, partly in section, of one form of the invention as applied to machines for the purposes before referred to, the thread-guide being shown in operative position in full lines and in inoperative position by broken lines; Fig. 2, a plan of a threadguide detached from its carrying means; Fig. 3, a plan of the devices shown in Fig. 1; Fig. 4, a similar view to that shown in Fig. 1; Fig. 5, a plan of a detached thread-guide as shown in Fig. 4:; Fig. 6, a transverse section of the arrangements shown in Fig. 4:; Fig. 7, an end elevation, similar to Fig. 1, of another arrangement of guide; Fig. 8, a plan of same; Fig. 9, an end elevation showing a slightly-different arrangement to that shown in Fig. 1; Fig. 10, a plan of same; Fig. 11, an end elevation of another different form to that shown in Fig. 1, designed specially for use in connection with wood rails; and Fig. 12, a plan of same.

In carrying out our invention with reference to the accompanying drawings, in which similar letters indicate like parts,o is the ordinary fixed rail of the spinning, doubling, or winding frame, and o a rail or bracket affiXed thereto in any suitable way. With reference to Figs. 1 to 3, we mount on the rail 6 metallic or like plates 0, arranged in convenient lengths to suit the character of the machine to which the improved thread-guide arrangements are applied. 'The plates 0 are provided with longitudinal projecting portions 0' at their under side and with longitudinal channels d, formed therein. At right angles to the channels d are slots d, corresponding in number with the number of spindles in the machine. Supporting the plates 0 are plates 0, arranged in suitable or continuous lengths, the front and back edges of which are bent over, so as to embrace the front and back edges of the plate 0, the bent-over portions allowing of a little transverse movement of the plates 0 in order to enable the thread-guides proper, f, to be adjusted centrally with the spindles of the machine. The plates 0 and e are provided with slots d to enable the adjustment to be made, and through these slots bolts 6!, screws, or the like may be passed to clamp the plates to the brackets or rails b when the thread-guides f are properly adjusted in themanner before referred to. The threadguides proper, f, are provided at their front ends with the usual twizzle or curled eye g, through which the thread may pass on its Way to the spindle, while at their rear ends each guide is provided witha projecting shank f, capable of freely resting in the longitudinal groove or channel (Z, as will be readily understood, being kept in such channel by the upper plate 0. It will be readily seen from Fig. 1 that the heel f of each threadguide f is when in its working position in contact with the projecting portion 0 of the plate 0, while when turned out of its position into the broken-line position it is entirely out of the way of the minder of the machine during the dofiing operation. It will further be understood that by means of the upper plate 6 no fly or fluff from the yarn or thread can gather about the horizontal portion f of the thread-guide, and therefore no interference with its proper action is possible. Each thread-guide may be turned from the operative to the non-operative position quite independently and returned to operative position, as may be required.

Referring now to Figs. 4 to 6, instead of arranging the thread-guides f to be turned up out of the way on an axis running longitudinally of the machine-frame we arrange each guide to be capable of being turned out of the way on a transverse axis. For this purpose the bottom plate 0 is provided with transverse channels h and at the rear side with cup-shaped portions It, and the thread-guide itself has at its rear enda ball-shaped portion it, while toward its forward end it is cranked at 71 ,the said ball-shaped portion preventing the guide being moved backward or forward toward or from the spindle, while the crank portion rests upon the forward portion of the plate 0 and holds the guide in operative position. When the guide is turned up, it is out of the way for dofling purposes. Similar means of adjustment transversely toward or from the spindle is adopted to that shown in Figs. 1 to 3.

Referring now to Figs. 7 and 8, we practically reverse the arrangement indicated in Figs. 1 to 3that is to say, plate 6 is next to the bracket 6, while plate 0 is farthest away from it. Instead of the heel f on the threadguide f the guide itself merely rests upon the front portion of the plate a.

In Figs. 9 and 10 an exactly similar arrangement to that indicated in Figs. 1 to 3 is employed, except that the plate a is hinged at e and has extensions 6 capable of being clamped between the rail a and rail or bracket 6. In this way the thread-guide f, together with the plates 0 and 0, may be turned upward into the broken-line position, as indicated.

Referring now to Figs 11 and 12, the threadguides f are provided intermedially with curled portions r1, through which are passed spindles 71, carried by the hinged thread-board c'", which in turn is hinged to a second threadboard 71, as indicated. Further, each threadguide is provided with a heel 7', adapted to engage with the rear side of a slot j, formed in the board '5, thereby holding the guide in operative position.

From the foregoing description it will be seen that we entirely dispense with the use of thread-guid es formed with screws at their rear ends and passed into wooden thread guiderails, as is commonly the case, while at the same time we provide improved thread-guiding arrangements in which the thread-guides are capable of being readily turned up about an axis arranged longitudinally or transversely of the machines to which they are applied. Further, such arrangements as we have described are of such a nature that the adjustment of several of them can be readily carried out toward or from the center of the spindles, as required, while they are free from the objections of thread-guides hitherto in use in that they will not catch fly or fluff that will interfere with their proper working.
